20	tn Heb “[it] restores life.” Elsewhere the Hiphil of שׁוּב (shuv, “return”) when used with נֶפֶשׁ (nefesh, “life”) as object, means to “rescue or preserve one’s life” (Job 33:30; Ps 35:17) or to “revive one’s strength” (emotionally or physically; cf. Ruth 4:15; Lam 1:11, 16, 19). Here the point seems to be that the law preserves the life of the one who studies it by making known God’s will. Those who know God’s will know how to please him and can avoid offending him. See v. 11a.
21	tn Traditionally, “the testimony of the Lord.” The noun עֵדוּת (’edut) refers here to the demands of God’s covenant law.
22	tn God’s covenant contains a clear, reliable witness to his moral character and demands.
23	tn Or “the [morally] naive,” that is, the one who is young and still in the process of learning right from wrong and distinguishing wisdom from folly.
